MACHINE-QILER;

ieoaees.

To all whom it may concern: 4 I i Q Be it known that L'GEORGE M. ROGERS, a

citizen of the United States, residing 'at lit] ' can be operated with either an electrical or .o

Chicago, in the .county of Cook and State of Illinois, have invented new and useful Tm mechanical timer and can be so arranged as to feed the required amount of oil to each;

bearing or machine element, and which will requirev but very slight attention on the part of the attendant,

The invention consists in the construction, combinatlon, and arrangement of devices, hereinafter descrlbed and claimed.

--In theaccompanying drawings :Figure I 1 is a vertical sectional view of anelectrically operated oiler constructed in accordance with my invention and showing,

the valves in raised, open position. Figs. 2 and Kara detail views. Flg. 4 is a diagrammatio elevation of an automobile motor, showing one of my improved elecwith an electric circuit and switchfor elec-' trically operated oilers arranged for -sup' plying oil to the motor and in. connection trically operating the oiler.

My improved oiler' comprises a cup 1 of suitable shape and dimensions and. which a is, here shown as having atapered lower "tit portion, the bottom .2 of the cup'being provided with a series of vertical oil discharge openings 3, each of which is counterbored and threaded at its lower end so that pipes i may be attached. to the bottom of thecup to convey oil frointhecup to the bearings A, cylinders B or' other parts .to be lubricated." automobile motor is here shown at C as connected to the oiler. llnone side qt the 'cup is a threaded opening 5 to which is'attached an' oil feed pipe 6 which'ser ves (to keep the cup sup-pliedwith liibricating oil 'from a suitable tank or otherreservoir.

The upper end'ot the cup is open and is internally threaded as at 7.

A casing 8 which is cylindrical in form is provided with an enlarged circular base 9 which is screwed into the upper end of the cup and closes the same. The base has ,a circular opening 10 of suitable diameter. A cap 11 is screwed on the upper end of the casing as at 12 and is provided on its upper side atthe center with a screw stud 13 which by engaging a threaded opening in a suitable s'upport D serves to hold the an upright position. v

A solenoid 14 is arranged" in,the casing head 15' thatbears on the bottom of the casing, an upper head 16, and a tubular core" oiler in and has a spool which comprises a lower I or sleeve17, the lower end of which extends I downthrough the central opening 10 of the bottom of the casing. andthe upper end "of which is. fitted in ;'a central counter bore 18 in the under-side of the cap. Insulators 19' are, arranged in openingsin opposite sides .of the cap and the terminals of the windings of. the solenoid pass through said insulators and are provided with connectors 20 for the attachment of conducting wires 21' of an electric circuit, which includes the windings of-the solenoid and also includes a switch 22 operated by a time mechanism, 22 and by means of which the circuit may be opened and closed at will. I

Ajplunger rod 23, which is made of steel is arranged to operate vertically in the tubular bore or sleeve of the solenoid and its lower end which extends intb the oil cup is provided withamember 24 to the under sideof hich a series'of valves 25 are attached, each valve havingna tapered lower end to close mom of the oil openings 3 ands being also provided with a centrally' arranged downwardly extending pin washer 27 is fitted loosely on the plunger to bear against the lower end of the tubular .core sleeve 17 and a spring 28 is coiled around. the'lower portionof thev plunger rod 23'and bears between the member 24 and the washer and serves, when the sole- 26, which acts as a guide for the valve. A

noi'd is deenergized', to move said plunger rod downwardly with the member 24 :and

valve 25 and close the latter in the openings bore of eachvalve, toclosely flush on the bottom ofthe oil cup when the plunger is lowered.

When it is desired to suppl'ylubricating' 3. Arubber gasket 29 is placed around the t oil to the bearings or other machine el'ements, the'e'lectri'ccircuit is closed by-means of the switch and" the solenoid energized,

" the plunger rod being thus moved up- I wardly with the member 24; and valves and opening the latter from the openings 3.

many valves and fee'd pipes may be provided as desired. a

*Theloiler maybe operated with the timer,

" eitherelectrically' or'me'chanically, and the timer' .can besetso'; as to give the proper kf'amoun t-of electric current and thus regu- --late-fthe quantity of oil fed through. each 'p pea l "Any suitable form of electrically ope'rated means may, within the; scope of the invention, be employed" for j actuating the plunger and its valves, 'instead of the sole 7 .noid, if desired.
